Switch Statements

Switch Statements

Switch Statements are a language feature.

In computer programming languages, a switch statement is a type of selection control mechanism used to allow the value of a variable or expression to change the control flow of program execution via search and map. Switch statements function somewhat similarly to the if statement used in programming languages like C/C++, C#, Visual Basic .NET, Java and exists in most high-level imperative programming languages such as Pascal, Ada, C/C++, C#, Visual Basic .NET, Java, and in many other types of language, using such keywords as switch, case, select or inspect. Switch statements come in two main variants: a structured switch, as in Pascal, which takes exactly one branch, and an unstructured switch, as in C, which functions as a type of goto.

Languages with Switch Statements include Java, JavaScript, C, C++, PHP, Go, C#, Swift, Objective-C, PowerShell, Dart, Groovy, CoffeeScript, Reason, X10, ABAP, Flow9, Angelscript, Apex

Example from JavaScript:

var animal = "dog" switch (animal) { case "dog": console.log("yay"); break; case "cat": console.log("oh"); break; }
